The Mersen T1048679 is a high-performance NH3L photovoltaic fuse-link designed specifically to protect high-voltage DC circuits in commercial and utility-scale solar installations. Part of the proven Mersen HelioProtection® HP15NH range, it provides dependable gPV protection for cables and equipment within photovoltaic groups and array-combiner systems.
This fuse-link combines a robust Size 3L body with DIN-type blades for secure direct mounting. Its specialist construction is designed to withstand the repeated current and temperature cycling encountered in photovoltaic applications while interrupting dangerous DC fault currents before they damage cabling, combiner equipment or inverter inputs.
With a rated current of 160 A, a voltage rating of 1500 V DC and a maximum breaking capacity of 150 kA DC, the T1048679 provides reliable protection for demanding solar power systems. Compliance with IEC and UL photovoltaic fuse standards makes it suitable for internationally specified renewable energy equipment.
High-voltage photovoltaic installations require specialist DC fuses capable of interrupting sustained fault currents safely. A correctly selected gPV fuse helps isolate short circuits and reverse currents before they damage solar array cables, combiner boxes, inverter inputs or associated distribution equipment.
The Mersen HP15NH range is designed for use as main fuse protection within groups of photovoltaic strings. Its high breaking capacity, durable construction and compliance with international PV standards make the T1048679 a dependable choice for renewable energy systems requiring long-term electrical protection.
